Difficulty with Gordonia bronchialis identification by Microflex mass spectrometer in a pacemaker-induced endocarditis.

ABSTRACT:

Introduction

This report describes the first case, to the best of our knowledge, of pacemaker-induced endocarditis due to Gordonia bronchialis.

Presentation

Pacemaker-induced endocarditis due to G. bronchialis infection was determined in a 92-year old man. This Gram-positive bacillus failed to be identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry technology, whereas the taxon was indexed in the database. 16S rRNA and rpoB gene sequencing were required to determine the correct strain identity.

Conclusion

Infections caused by G. bronchialis remain a rare phenomenon affecting immunocompromised patients and/or medical device carriers. Molecular tools may be necessary to ensure accurate identification.
